Aggressive behavior in healthcare facilities represents a serious threat to safety and health in healthcare facilities, and violence against medical staff is constantly increasing. Within this thesis the aggression of patients towards nurses and technicians was explored, with a focus on forms of aggression and their impact on employees in the health sector. The research was conducted among 225 respondents, and the prevalence and consequences of aggressive incidents on work efficiency and mental health are considered. This research paper analyzes patient aggression towards nurses and technicians, focusing on the types of aggression and their impact on employees in the healthcare sector. Based on research conducted among 225 participants, the paper examines the prevalence and consequences of aggressive incidents on work performance and mental health. The results show that nurses and technicians are most frequently exposed to verbal aggression, while physical violence and destructive forms of aggression are relatively rare. The study reveals that 63.6% of participants experience aggression, with the majority of reported cases involving verbal attacks. Regarding aggression reports, a significant number of participants do not report incidents, which may be due to fear of repercussions or the belief that reports will not lead to changes. Furthermore, only 4.9% of participants believe that aggressors face consequences, indicating a need for improvements in the reporting system. The study also shows that aggression negatively affects employees' work ability and mental health. More than 14% of participants report a decrease in their ability to perform work tasks due to aggression, while an increased number of sick days confirms serious health consequences. Education on the prevention and management of aggressive behavior is recognized as crucial for reducing the number of aggressive incidents and improving the work environment. In conclusion, the paper highlights the need for enhancing reporting policies, increasing transparency and support for employees, and implementing preventive measures to reduce the negative impacts of aggression and improve the work environment in the healthcare sector.
